Would a normal person say this or am I overthinking?

Me and my husband have a toddler and a baby on the way. The baby was crying and he took the pillow and pretended like he was going to put the pillow over her head. And he said" he said hush I'm going to suffocate you". I immediately grabbed the baby and cuddled. And I started cussing him out. He said he was playing but now I don't look at him the same anymore. Now he's playing victim like I'm over thinking it.
